Mounting
This information must be read and followed carefully
to prevent accidents and injuries during mounting.
WARNING
Check tire and wheel carefully before
mounting. Make sure the tire bead diameter
and wheel diameter match exactly. Con-
sult the Rubber Manufacturer’s Association
for approved rim widths for tire sizes. Mis-
matched tires and wheels explode.
CAUTION
Never Mount a tire and wheel handed to
you by anyone without checking both tire
and wheel for damage and compatibility. Be
extra cautious of persons without knowl-
edge of tire service. Keep by-standers out of
service area.
WARNING
Never mount a damaged tire. Never mount a
tire on a rusty or damaged wheel. Damaged
tires and/or wheels may explode.
CAUTION
If you damage the tire bead during mount-
ing, STOP!, remove the tire and mark it as
damaged. Do not mount a damaged tire.
1. Inspect the wheel closely for damage. Clean the
wheel and remove any light corrosion or rubber residue
(Figure 12). Do not attempt to service heavily corroded
wheels.
Figure 12 - Inspect and Clean the Wheel
2. Inspect tire for damage, paying close attention to
the beads. Verify size match between tire and wheel
(Figure 12).
3. Lubricate tire beads liberally with tire manufacturer
approved lubricant (Figure 13).

above the rear extension of the mount/demount tool
and below the front knob (Figure 14).

5. Depress table top pedal and rotate the wheel to
mount the lower bead. Use the drop center of the wheel
to reduce the tensional force on the bead by pressing
down on the tire directly across from the mount tool.
Rotate table top until lower bead is fully mounted.
6. For top bead, rotate the table top until the valve
stem is directly across from the mount tool. Lift the
upper bead up and over the rear of the mount tool.
With your left hand press down on the tire between the
mount tool and the valve stem to hold the tire in the
drop center. Depress the table top pedal and rotate the
tire until the bead is mounted. Continue to press down
on the tire during the remaining mounting process.
